    A Pretty Uneventful Week; Long-Range Changes

    It is getting to the time of year when wild weather becomes less likely and the weather turns more mundane. That pretty much sums up the rest of the workweek in the West.

    A large portion of the West should have a good look at the lunar eclipse later Monday night. The exception will be along the central and northern California coast, with low clouds developing and also clouds along the Northwest coast. There will be high-level clouds in the rest of the Northwest, but most should be able to see the eclipse through those clouds.

    What precipitation that does occur this week will be mainly in the Northwest and far northern California. Nothing out of the ordinary. Thursday will probably be the wettest day with some snow likely in the Cascades, especially above pass level.

    Farther south, there will be a couple of periods when there will be more clouds around than other days, but that is about it. The exception will be in Southern California where more extensive marine clouds will show up Wednesday through Friday as temperatures cool down. The San Joaquin Valley will probably have the least change of anyone with just minor temperature fluctuations all week.

    If you have taken a look at next week, you may have noticed that the GFS operational model is trying to bring a much bigger change in the Tuesday/Wednesday time period.

    Here it is for next Tuesday afternoon.

    However, before you get too excited about rain in California with snow in the Sierra, know this; the European is much, much different. It has a trough moving through, but mainly through the Northwest and northern California. Instead of a near 550 dm cut off low, the European has a west-southwest flow with 576 dm heights. That is a huge difference, not only saying it will not rain or snow, but also temperatures would be considerably warmer.

    With history on the side of the European, I am certainly not going to go out an by the GFS at this time. This is an area to watch but I would not be surprised if the GFS changes its look.
